摘要

In one aspect, a system for detecting and classifying direct response advertisements includes an advertisement candidate segment generation unit for generating an advertisement candidate segment for an advertisement section detected from a broadcast stream, a matching unit for determining whether the advertisement candidate segment matches an advertisement segment stored in an advertisement database (DB), a direct response advertisement determination unit for determining whether the advertisement candidate segment is a direct response advertisement if it is determined by the matching unit that an advertisement segment matching the advertisement candidate segment is not present, and a direct response advertisement grouping unit for grouping the advertisement candidate segment with advertisement segments that are direct response advertisements stored in the advertisement DB.

1. A system for detecting and classifying direct response advertisements, comprising:
a receiver for receiving a broadcast stream; an advertisement candidate segment generation unit for generating an advertisement candidate segment for an advertisement section detected from the received broadcast stream; a matching unit for determining whether the advertisement candidate segment matches an advertisement segment stored in an advertisement database (DB), wherein determining whether the advertisement candidate segment matches the advertisement segment comprises determining that a fingerprint of at least a portion of the advertisement candidate segment matches a fingerprint of at least a portion of the advertisement segment; a direct response advertisement determination unit for determining whether the advertisement candidate segment is a direct response advertisement if it is determined by the matching unit that an advertisement segment matching the advertisement candidate segment is not present; and a direct response advertisement grouping unit for grouping the advertisement candidate segment with advertisement segments that are direct response advertisements stored in the advertisement DB if it is determined by the matching unit that an advertisement segment matching the advertisement candidate segment is present and the matching advertisement segment is a direct response advertisement; and a direct response advertising registration unit for storing the advertisement candidate segment determined to be the direct response advertisement by the direct response advertisement determination unit as an advertisement segment that is the direct response advertisement in the advertisement DB.
